giving users access to specific databases

Hi,

I'm hoping someone can tell me how to go about this, or if a solution is
even possible with my current set up. I realize this question may go beyond
pure postgres topics and have to do more with how my hosting company has
their servers configures, but this group seemed like my best option for
help. If anyone has suggestions on what other groups might be helpful to
post this question to, I would really appreciate it.

I do my database & application work on a shared Linux server provided by my
hosting company. It appears they have just one installation of postgres on
the server and that all of their customers on that server are able to create
databases and users under their account. I'm not quite sure how they have
enabled specific user accounts for access to my specific part of the server,
but I do know that when I log in I have access to a cpanel interface, email
configuration, all of my files on the server, access to create new postgres
databases and a link to phpPgAdmin. The difficulty I have is that in order
to give another of the developers access to a specific database, I must give
them the username and password to my entire account on their server. I've
spent weeks corresponding with them on how I can give individual access to
just a specific database. We finally tried installing a separate instance
of phpPgAdmin in my web directory. I can get access to my databases through
this, but it turns out I still need to use my main username and password to
access the databases since we realized they needed to tighten security so
other people on the server couldn't get access to my databases. Below is a
copy of the last email I got from the hosting company. If anyone has any
suggestions on what would fix this problem I would really appreciate it. I'm
not set on having to use phpPgAdmin, but I would like some sort of graphical
interface available so less-technical users can update information in the
database without having to learn sql.

Subject: Separate login for phpPgAdmin
The only way with phpPgAdmin is to allow you access to all databases
including those owned by you. This can cause a security issue where others
would have access to your database as well. Unlike phpmyadmin, phpPgAdmin
does not seem to allow you to login to a database with a database username
unless the above option is enabled and therefore creating a security risk.
The way Postgres is set to label owners it uses your CPANEL login as the
owner which is different than how MySql tracks the databases. Due to this
you would not be able to use phpPgAdmin with other users.

Thanks in advance,
